' ELUSH IANK VALVE.

Application filed May. 117

To a ll whom it 'may conoem:

'Be it known that I, Srrnr1iiN'KNn1 rnL, a citizen of Germany, and a residentefficranton, 1 in the county of Lackawannaand State of Pennsy-lvania,='have invented a new and Improved Flush-Tank Valve, ofwhich the following is a description. I

My invention relates to the discharge valves of flush tanks and the invention has for its general object to provide a tank valve adapted to be lifted by a pull exerted on a chain, lever, or the like, and reflecting practical considerations looking to the production of a weighted valve characterized by accuracy of operation and the facility with which the parts may be produced and assembled as well as to obtaining simplicity and durability of construction.

The nature of the invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompany ing drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a side elevation of a flush tank valve embodying my invention, a portion of the valve and flush pipe being shown in vertical section;

Figure 2 is a vertical section through the valve and flush pipe;

Figures 3 and 4 are horizontal sections respectively on the lines 33 and 4 4r-, Figure 1.

In the illustrated example the numeral 10 indicates a flush pipe and 11 a disk forming part of my improved valve, said disk adapted to seat on top of the pipe 10 to efiect a closure of the same.

The valve has a stem or shank 12 adapted to be connected in practice with any valvelifting means such as a chain, lever, or the like, said stem being secured at its lower end in a socket 13 disposed in a central vertical hole 15 in a cap plate 16 secured to the disk 11 at the top. The hole 15 is undercut or of enlarged diameter at the lower portion and the socket 13 has an enlarged lower end 14 accommodated in said undercut portion of the hole 15.

Screws 17 or equivalent fasteners extend through the cap plate 16 and disk 11 and are received in threaded sockets 18 in the upper surface of a disk 19 positioned at the under side of the disk 11. The disk 19 is 1922. Serial No. 561,682.

cofsmaller diameter than the disk 11 and is adapted to' enter in vthe upper end of the flush pipe 10. The screws 17 serve to clamp thecap plate 16 down on the disk 11- and serve to draw the under disk '19 against the underside of the disk 11. "With the cap plate 16 in positionthe socket 13 is held by the lower EPOIlIlO'H 1 1 against detachment in an upward direction and is limited in its downward movement by the disk 11. Sufiicient play, however, is permitted the socket 13 and its lower part 14 relatively to the disk 11 and cap plate 16 for the valve to seat itself firmly on the pipe 10 not being limited by a rigid connection with the shank 12.

To the disk 19 I secure a skeleton frame 20 composed of crossed U-shaped wires, the upper ends 21 of which are passed through the sides of the upwardly extending rim portion of the disk 19 and bent against said rim as at 21 to hold the frame 20 against detachment. The rim of the disk 19 has vertical grooves 22 in which the wires forming the frame 20 are accommodated so that the wires lie approximately flush with the outer periphery of said rim portion. The frame 20 acts as a guide frame to hold the valve against the material displacement of the valve so that the valve will always be required to seat upon the flush pipe 10.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:

1. A flush tank valve including a disk adapted to seat on a flush pipe, a cap plate on said disk, a stem above the cap plate, an element on the stem and having an enlarged lower portion, said cap plate having a hole receiving said element and undercut to accommodate said enlarged lower portion of the element, said element being permitted play relatively to the valve and cap plate so that the latter may rock relatively to the disk to seat itself on the flush pipe, a disk at the under side of the first-mentioned disk and having a depending frame adapted to enter the flush pipe, and fastener screws extending through said cap plate and the firstmentioned disk, the second-mentioned disk having threaded sockets receiving said screws so that the disksand cap plate are drawn in close relation.

2. A flush tank valve including a disk adapted to seat on a flush pipe, a cap plate at the upper surface of said disk provided With a socket formed With an undercut section,means to detachably hold the cap on the disk, a stem, a head threaded to said stem, said head being formed with an enlarged end, said enlarged end being housed in said undercut portion of said socket, said head being free to move in said socket and limited in its upward and downward movement by the disk and the restricted section I of the socket respectively.

3. A flush tank valve of the character described comprising a disk adapted to seat on a tiush pipe, a cap provided with a socket on said disk,a circular plate presenting a plurality of threaded sockets at the under surface of said disk, said cap and said disk being provided with openings adapted to align with the threaded sockets in the circular plate, means extending through said openings and into said sockets for securing the cap, disk and plate together, a frame secured to said circular plate and normally in said pipe, a head provided with a threaded bore arranged to freely move in the socket through said cap, and a threaded stem connected With said head.
